嗜中性粒细胞增多


背景上的RBC是正常的,但有大量嗜中性粒细胞存在,主要因嗜中性粒细胞的增多而使WBC(白细胞)计数增高,提示有炎症或感染的存在。类白血病反应(非白血病)中,WBC(白细胞)计数非常高(>50000)。这种反应因嗜中性粒细胞中碱性磷酸酶(LAP)的大量存在而和恶性的白血病相区别。
The RBC's in the background appear normal. The important finding here is the presence of many PMN's. An elevated WBC count with mainly neutrophils suggests inflammation or infection. A very high WBC count (>50,000) that is not a leukemia is known as a "leukemoid reaction". This reaction can be distinguished from malignant WBC's by the presence of large amounts of leukocyte alkaline phosphatase (LAP) in the normal neutrophils.
